Understanding Security Challenges and Defending Access Control Models for Cloud-Based Internet of Things Network

Access control is one of the most important measures for protecting information and system resources because it prevents unauthorized users from gaining access to protected objects and legitimate users from exceeding their access rights. This paper provides an in-depth exploration of the security challenges posed by the confluence of Internet of Things (IoT) networks and cloud-based architectures, with a particular focus on Access Control Models (ACMs). As the integration of IoT devices with cloud services becomes more pervasive, securing access to resources and data has emerged as a critical area of concern. To address this, we delve into the principles of Access Control and their applications within a Cloud-IoT Architecture. The paper dissects popular ACMs, exploring their strengths, limitations, and suitability for securing Cloud-IoT networks. Along with these the comprehensive analysis of the prevalent Cloud Security Challenges are presented, highlighting the vulnerabilities in current ACMs and proposing potential mitigations. In addition, open research challenges are identified, underlining the need for further investigation and development in this area. The goal of this work is to provide a thorough understanding of the issues and threats in this domain and contribute to the advancement of robust, secure, and efficient access control mechanisms for the evolving landscape of Cloud-IoT networks.
